Why convert JPG to WebP?
WebP was designed specifically for the web. Its lossy mode uses VP8 prediction (originally from the WebM video codec), which compresses photographs significantly more efficiently than the 1992-era DCT used by JPG. The end result: smaller files, faster page loads, and better Core Web Vitals scores.
WebP is now supported by every major browser including Safari (since 14.0), so the historical compatibility excuse no longer applies. For photographs in particular, the savings are dramatic — a 1.2 MB JPG hero image often compresses to 700–800 KB as WebP without any visible quality loss.
The conversion is one-way safe: you keep your originals, upload the JPGs, and download a ZIP of WebPs. Drop them into your web project and update your <img> tags or <picture> sources.

JPG to WebP — Frequently Asked Questions
Is the JPG to WebP converter really free?
Yes — completely free, with no signup, no credit card, no watermarks, and no file count limits. The full feature set is available without any account.
Are my JPG files private?
Yes. Files are stored in a private directory outside the web root, never shared with anyone, and deleted immediately after you download your ZIP.
How many JPG files can I convert at once?
Up to 20 JPG files per batch, with a maximum of 25 MB per file. There are no limits on the number of batches you can run.
Does the converted WebP keep the same image quality?
Quality is essentially indistinguishable from the JPG source at typical viewing sizes. WebP uses lossy compression, but the quality settings are tuned for high fidelity, so the conversion produces visually identical results for almost all images.
Will the WebP files work in Safari?
Yes. Safari has supported WebP since version 14.0 (released in 2020), and every other major browser has supported it for years. WebP is now safe to use as a primary web image format.
